Do not include this Slide.

This template is a guide for preparing power points presentations. The information requested is important and should be provided in generally the same sequence and same format. But each presentation must be tailored for the specific segment being presented. Some slides can be eliminated and sometimes extra slides will be necessary to best convey the background and backup data needed to make the case for the LSAC Assignment. Pictures are generally a very good method for communicating information on a particular feature or defect being evaluated; captions for photos should be provided.

Some of the additional summary type slides will eventually be produced directly from the LST but until then you will have to cut and paste the data / graph into the power point.

Adjust font size, color, layout, tables, etc. as needed to improve the presentation. Do not overload your slides with too much information; It is better to add a slide.

Don’t be surprised to see future revisions to the Power Point.

The power point for the SOG will likely be a subset of this power point.
